Definitions
- the object of the present invention is to provide a subassembly integrating the overspeed limitation, with another function of regulation, namely the detection of the pressure drop by performing the combination of these two functions in the same device where a fixed fur of the pressure drop detector serves as a housing for the movable drawer of the overspeed limiter in order to obtain increased miniaturization of the modular sub-assembly.
- An overspeed limiter 8 receiving for input information the rotational speed N of the turbomachine which drives it is called upon to reduce the flow rate in the injection circuit 3, when an overspeed threshold is reached in order to return the system at its nominal speed, according to an operating mode which will be detailed later.
- the invention relates to the embodiment of the module referenced 9 combining the pressure drop detector 4 and the overspeed limiter 8 and their respective fuel inlet and outlet pipes.
